NUMBER: 160 MODULE: onedspec.standard SYSTEM: V2.9 DATE: Thu Oct 17 09:22:06 MST 1991 FROM: valdes BUG: If the calibration bandpasses are less than a pixel wide the flux summation is incorrectly done when both endpoints are within the same pixel; the code assumed that the two endpoint pixels were not the same. Generally the calibration data, in onedstds$, has much larger bandpasses than typical spectra and so this bug has not be seen except in one reported case where a private calibration file with very small bandpasses was used. STATUS: Fixed in V2.10. The workarounds are to revise the calibration file to larger bandpasses (if using a private version), resample the spectra to smaller dispersion, or, the best choice, specify the bandpass widths and separations in the task to override the calibration file bandpasses and interpolate the calibration file data. NUMBER: 183 MODULE: doargus, dohydra, dofibers, skysub SYSTEM: Newimred, V2.10.0, V2.10.1 DATE: Wed Sep 23 15:57:40 MST 1992 FROM: valdes BUG: When using the skyedit option to review and eliminate bad sky apertures there is a limit to the number of sky apertures that can be retained. Exceeding this limit can cause the CL to crash. The limit is determined by how many aperture numbers can be fit into 160 characters in a string of the form 11,12,13,...; for 2 digit aperture numbers this would be a little over 50 sky apertures. The workarounds are to use less than about 50 sky apertures or to not use the sky edit option. STATUS: Planned to be fixed in V2.10.2.
